An ideal gas heat engine operates in Carnot cycle between `227^@C` and `127^@C`. It absorbs `6.0 xx 10^4 cal` of heat at high temperature. Amount of heat converted to work is :

A

`2.4xx10^(4) cal`

B

`4.8xx10^(4) cal`

C

`1.2xx10^(4) cal`

D

`6.0xx10^(4) cal`

Text Solution

Verified by Experts

The correct Answer is:
C
`eta = (T_(2)-T_(1))/(T_(2))=(500-400)/500=1/5`
`:. W=etaxxQ=1/5xx6.0xx10^(4)=1.2xx10^(4)cal`
